❔ Calling async method

Hi guys. I tried to call this AzureAPI class in main program. But I got a error. I want to call this string Result in main program and display it. How can I call this class and get a result in a place where I called.

It's not a static method So it needs an instance to be called on

You need to create an object of AzureAPI so you can call the method or convert the method to be static

I changed the method to static.

itgel9462OP•2y ago

What does this mean?

Jorge Morales•2y ago

it means the access level is restrictive, did you change the method to be private? because your first screenshot showed it was public

itgel9462OP•2y ago

Currently like this. But after I changed to static, string Result got the error.

public static async Task You removed the public for some reason So it defaulted to private

Jorge Morales•2y ago

apart from that, the Result property has to be static as well

Angius•2y ago

Or... don't make it static

Jorge Morales•2y ago

because from a static method you can only access another static members in the class

Angius•2y ago

And instantiate the object

Jorge Morales•2y ago

that's an easier approach I think

Angius•2y ago

That way Result won't have to be static And we'll have proper OOP Instead of funky pseudo-global variables Or, even better, just return the string from this method Instead of using a property

After changed Public static string Result, I got this error. I want to display this string in textbox. I want to do it like this.

I recommend brushing up on the basics What's static, what's an instance, etc

Jorge Morales•2y ago

I agree, I think you have to review the basics of C#, so you can make the proper changes for your code if you have git enabled, you can undo your changes and apply this, to create an instance of the class

Two ways I can see it working

class Foo
{
    public static Task<string> Unga(Bunga boo)
    {
        return $"Stuff and things and {boo}";
    }
}

class Foo
{
    public static Task<string> Unga(Bunga boo)
    {
        return $"Stuff and things and {boo}";
    }
}

var stuff = await Foo.Unga(sdfsdf);

var stuff = await Foo.Unga(sdfsdf);

class Foo
{
    public string Result { get; set; }

    public Task Unga(Bunga boo)
    {
        Result = $"Stuff and things and {boo}";
    }
}

class Foo
{
    public string Result { get; set; }

    public Task Unga(Bunga boo)
    {
        Result = $"Stuff and things and {boo}";
    }
}

var f = new Foo();
await f.Unga();
var stuff = f.Result;

var f = new Foo();
await f.Unga();
var stuff = f.Result;

IMHO the first one is better

Ok guys. Thank you so much. I will try this. Thank you

itgel9462OP•2y ago

I called the method in main program. And got this. Do you guys know what that is and what I should do

Jorge Morales•2y ago

not really, looks like the SpeechRecognizer class comes from a library and it is expecting to find something and fails? I'm just guessing at this time, sorry
